### HAZARD SEVERITY INDEX CALCULATION ###
The files for calculating a hazard severity index at yearly and country resolution based on events exceeding a certain percentile threshold are contained under "temperature_calculations", "precipitation_calculations", and "windspeed_calculations". They follow the format outlined in the example file, "CDHR2019_yearly_calculations_example.r".

The resulting R data frames are found in "Hazard_Severity_Data". These files contain the number of days exceeding a certain percentile threshold (denoted with "pctl") per year in each country, normalized by the number of grid cells the data was aggregated from (as detailed in the "Methods" section of the article).

The specific modules used to execute these scripts are located in "CDHRmodules.sh".
